And the water vapor temperature is higher, and the direct discharge can scald the user.

Disclosure of Invention

The embodiment of the utility model provides a steaming and baking box, which is used for solving the problems of high humidity and high temperature of steam discharged by the steaming and baking box.

In order to achieve the above object, the embodiment of the present utility model adopts the following technical scheme:

the utility model provides a steaming and baking box, which comprises a shell, an inner container, a condensing pipe and a condensing water box. The casing has a receiving chamber in which the inner container and the condensate box are located. Wherein, the inner container is provided with a steaming and baking cavity, and food to be cooked can be placed in the steaming and baking cavity. The inner container is also provided with a first air outlet hole which is communicated with the steaming and baking cavity, and the utilized or surplus steam in the steaming and baking cavity can be discharged from the steaming and baking cavity through the first air outlet hole.

The steaming oven can be used for baking food and steaming food. When the steaming and baking oven is used for baking food, the steaming and baking oven can utilize the electric heating element to change electric energy into heat energy, so that the temperature of the steaming and baking cavity is increased, and then the food in the steaming and baking cavity is baked. When food is steamed, water is fed into the steam generating assembly, which rapidly heats the water to generate a large amount of steam. The steam generated by the steam generating assembly enters the steaming and baking cavity to heat the food in the steaming and baking cavity.

When the steaming oven utilizes high-temperature steam to cook food, the utilized steam or the surplus steam in the steaming and baking cavity needs to be discharged from the steaming and baking cavity. The high temperature and high humidity water vapor is directly discharged into the kitchen, so that the air humidity in the kitchen space is increased, and the high temperature water vapor may scald a user.

Solves the problems of high temperature and high humidity of the vapor directly discharged from the steaming and baking cavity. In this way, the cooled water vapor is discharged from the steaming and baking chamber when it encounters the steaming and baking panel. Due to the reduced temperature and humidity of the cooled water vapor. Thus, when the cooled water vapor encounters the lower temperature toaster panel, water drops condensed on the toaster panel will be reduced. In addition, the water vapor is cooled by cold water, so that the condition that the water vapor scalds a user can be avoided.

The present application provides a steaming oven, as shown in fig. 1, the steaming oven 100 has a cabinet 1 and a liner 2. The housing 1 has a receiving chamber 10, and the liner 2 is located in the receiving chamber 10 of the housing 1. As shown in fig. 2, the inner container 2 has a steaming and baking chamber 20, and food to be cooked can be placed in the steaming and baking chamber 20. The inner container 2 is also provided with a first air outlet hole 201 (see fig. 1), the first air outlet hole 201 is communicated with the steaming and baking cavity 20, and the utilized or surplus water vapor in the steaming and baking cavity 20 can be discharged from the steaming and baking cavity 20 through the first air outlet hole 201.

Based on this, a brief description will be given of a process of cooking food in the steam oven 100. The steaming oven 100 can cook food as well as roast food. When the steaming and baking oven 100 is used for baking food, the steaming and baking oven 100 can utilize an electric heating element, for example, a resistance wire is electrified to generate heat, so that the electric energy is changed into heat energy, the temperature of the steaming and baking cavity 20 is increased, and then the food in the steaming and baking cavity 20 is baked until the food is baked. When food is steamed, water is fed into the steam generating assembly, which rapidly heats the water to generate a large amount of steam. The steam generated by the steam generating assembly enters the steam cavity 20 to heat the food in the steam cavity 20.

As can be seen from the above, the steaming oven 100 can either cook food or cook food. In the case where the steaming oven 100 uses steam to cook food, the steam used or the surplus steam in the steaming cavity 20 needs to be discharged from the steaming cavity 20. The high temperature and high humidity water vapor is directly discharged into the kitchen, so that the air humidity in the kitchen space is increased, and the high temperature water vapor may scald a user. In addition, water vapor is easily condensed on the panel of the steaming oven 100 to generate water drops when it is cooled, and the water drops drop on the cabinet, so that a problem of immersing the cabinet occurs.

In order to solve the problem of high temperature and high humidity of the directly discharged water vapor, as shown in fig. 3 (fig. 3 is an enlarged view of a in fig. 1), the present application provides a steaming oven 100 further comprising a condensation pipe 3 and a condensation water box 4. Wherein, the condensing tube 3 is communicated with the first air outlet 201, so that the steam in the steaming and baking cavity 20 enters the condensing tube 3. The condensate box 4 is located in the receiving chamber 10, and the condensate box 4 has a water storage chamber 40, the water storage chamber 40 for storing cold water.

On this basis, the condensation duct 3 penetrates the condensation box 4, and the portion of the condensation duct 3 located in the water storage chamber 40 can be in direct contact with the cold water in the water storage chamber 40, so that the cold water in the water storage chamber 40 cools the steam in the condensation duct 3.

Thus, when the steaming oven 100 cooks food using high temperature steam, the steam used in the steaming cavity 20 or the surplus steam in the steaming cavity 20 may enter the condensation duct 3 through the first air outlet 201. Since the condensation duct 3 is located in the condensation box 4, the condensation duct 3 can be in direct contact with the cold water in the water storage chamber 40. Therefore, the cold water in the condensation duct 3 can cool down the water vapor in the condensation duct 3, so that the temperature of the water vapor from the condensation duct 3 is reduced.

In addition, during the process that the water vapor in the condensation pipe 3 is cooled by the cold water, the water in the water vapor encounters the pipe wall of the condensation pipe 3 with a lower temperature, and is condensed into water drops on the pipe wall, and the water vapor discharged from the condensation pipe 3 is reduced in temperature and humidity. Thus solving the problems of high temperature and high humidity of the water vapor directly discharged from the steaming and baking chamber 20.

In this way, the cooled water vapor is discharged from the steaming and baking chamber when it encounters the steaming and baking panel. Due to the reduced temperature and humidity of the cooled water vapor. Thus, when the cooled water vapor encounters the lower temperature toaster panel, water drops condensed on the toaster panel will be reduced. In addition, the water vapor is cooled by cold water, so that the condition that the water vapor scalds a user can be avoided.

As can be seen from the above, in order to solve the problems that the high temperature and high humidity steam in the steaming and baking chamber 20 is directly discharged during the steaming and baking process of the food by the steaming and baking oven 100, the humidity in the kitchen space is increased or the user is scalded by the high temperature steam. The steam oven 100 includes the above-described condensation duct 3 and condensation box 4 for cooling the water vapor.

Based on this, in order to enable the water vapor in the steaming and baking chamber 20 to be discharged into the condensation duct 3, as shown in fig. 4, the steaming and baking oven 100 further includes an air inlet duct 31, one end of which is communicated with the first air outlet hole 201 of the inner container 2, and the other end of which is communicated with the first end 301 of the condensation duct 3.

In this way, the steam in the steaming and baking chamber 20 can be discharged into the air inlet pipe 31 through the first air outlet hole 201, further enter the condensation pipe 3 along the air inlet pipe 31, and then be cooled by the cold water in the condensation water box 4.

On the basis, as shown in fig. 4, the steaming and baking oven 100 further comprises an air outlet pipe 32, one end of the air outlet pipe 32 is communicated with the second end 302 of the condensing pipe 3, and the other end of the air outlet pipe 32 is used for discharging the steam cooled by cold water. In this way, the vapor in the steaming and baking cavity 20 can be ensured to continuously enter the condensing tube 3 through the air inlet tube 31 and be discharged through the air outlet tube 32 after the cold water is cooled, so that the vapor in the steaming and baking cavity 20 can be ensured to be discharged in time.

As described above, the condenser tube 3 cools the water vapor in the condenser tube 3 by the cold water in the condensate box 4. Accordingly, in order to supply water to the condensate box 4, as shown in fig. 4, the steam oven 100 further includes a water inlet pipe 41, one end of the water inlet pipe 41 is connected to a water source, the other end of the water inlet pipe 41 is communicated with the water storage chamber 40 of the condensate box 4, and the water inlet pipe 41 is used to introduce cold water into the water storage chamber 40.

In this way, the water inlet pipe 41 can supply cold water to the condensation box 4 to cool the water vapor in the condensation pipe 3.

In addition, as is clear from the above, in the process that the water vapor in the condensation pipe 3 is cooled by the cold water in the water storage cavity 40, the water in the water vapor encounters the pipe wall of the condensation pipe 3 with a lower temperature, and is condensed into water drops on the pipe wall.

In this case, in order to allow the water droplets condensed on the wall of the condensation duct 3 to be collected and reused. The condenser tube 3 may be arranged such that at least part of the first end 301 of the condenser tube 3 is lower than the second end 302 of the condenser tube 3.

The first end 301 of the condensation duct 3 may be at least partially lower than the second end 302 of the condensation duct 3, and a part of the orifice of the first end 301 may be lower than the orifice of the second end 302, or the orifice of the first end 301 may be all lower than the orifice of the second end 302, which is illustrated in the following description with reference to the accompanying drawings.

In some embodiments of the present application, as shown in fig. 5, a portion of the orifice of the first end 301 of the condenser tube 3 is lower than the orifice of the second end 302. In this case, the water droplets that condense on the wall of the condenser tube 3 will flow under the influence of gravity along the wall of the condenser tube 3, from the second end 302 in a direction towards the first end 301. And flows into the air inlet pipe 31, and then flows back into the steaming and baking cavity 20 of the liner 2 along the air inlet pipe. The electric heating component arranged at the bottom of the inner container 2 can heat the water which flows back into the steaming and baking cavity 20 and form water vapor, so that the water can be reused.

In other embodiments of the present application, as shown in fig. 6, the orifice of the first end 301 of the condenser tube 3 is completely lower than the orifice of the second end 302. In this case, the reason why the condensing tube 3 allows the condensed water to flow back into the steaming and baking chamber 20 is the same as above, and a description thereof will not be repeated.

As can be seen from the above, the cold water in the water storage chamber 40 of the condensate box 4 can cool the high-temperature vapor in the condensation duct 3. Based on this, it can be understood that when the high-temperature water vapor in the condensation duct 3 is cooled by the cold water in the water storage chamber 40, the cold water exchanges heat with the high-temperature water vapor, which causes the temperature of the cold water in the water storage chamber 40 to be continuously increased, which results in a decrease in the cooling effect of the cold water. Therefore, it is necessary to replace the cold water in the water storage chamber 40 in time, ensuring that the high-temperature water vapor in the condensation duct 3 can be cooled effectively.

In this case, as shown in fig. 7 (the water storage chamber 40 is not shown), the steaming and baking oven 100 further includes a water outlet pipe 42, one end of which is communicated with the water storage chamber 40 of the condensate box 4 for discharging water in the condensate box 4.

In this way, after the cold water in the water storage chamber 40 of the condensate box 4 exchanges heat with the high temperature vapor in the condensate pipe 3 for a long period of time, the water having a temperature increased in the water storage chamber 40 of the condensate box 4 can be discharged through the water outlet pipe 42. And cold water can be refilled into the water storage chamber 40 through the water inlet pipe 41 communicated with the water storage chamber 40, thereby ensuring that the high-temperature water vapor in the condensing tube 3 in the water storage chamber 40 can be effectively cooled.

As can be seen from the above, when the steaming oven 100 uses high-temperature steam to cook food, a large amount of high-temperature steam exists in the steaming cavity 20. Thus, as shown in fig. 7, the steaming oven 100 provided by the present application further comprises a steam generating assembly 5, wherein the steam generating assembly 5 is connected with the water source and/or the water outlet pipe 42, and the steam generating assembly 5 is further connected with the inner container 2. The steam generating assembly 5 is used for generating high-temperature steam and inputting the high-temperature steam into the inner container 2, and then steaming and roasting food in the cavity 20.

When the steam generating module 5 is connected to the water source, the steam generating module 5 may be connected to the water source by a connection pipe. The water source directly supplies water to the steam generating assembly 5 so that the steam generating assembly 5 can generate high temperature water vapor. On the basis, a valve can be additionally arranged on the connecting pipe to control the on-off of water flow, so that the water vapor generation of the vapor generation assembly 5 can be controlled. When the water source is used for supplying water to the steam generation assembly 5, the steam generation assembly 5 is connected with the water source by using the connecting pipeline, so that the structure is simple, and the maintenance is convenient.

Alternatively, the steam generating assembly 5 is connected to the outlet pipe 42, i.e., the water in the condensate box 4 serves as a water source. In this case, since the water in the condensate box 4 exchanges heat with the high-temperature water vapor, the water temperature in the condensate box 4 is relatively high, which corresponds to the preheating of the cold water in the condensate box 4 by the high-temperature water vapor in the condensate pipe 3. In this way, the water temperature is higher, so that the working time of the steam generating assembly 5 for heating water and forming steam is shortened, and the effect of saving electric quantity is further achieved.

Alternatively, the steam generating assembly 5 is connected to both the water source and the water outlet pipe 42, in which case the steam generating assembly 5 is connected to the water source by a connection pipe, and the steam generating assembly 5 is connected to the water outlet pipe 42 by a connection pipe. On the basis, a valve or a water pump can be additionally arranged on the connecting pipe. In this way, the steam generating assembly 5 can be selectively supplied with water by controlling the opening and closing of the valve or the start and stop of the water pump. In this way, the reliability of the steam generating module 5 can be improved, and the steam generating module 5 can be ensured to be provided with a water source so as to generate steam.

As shown in fig. 7, the steaming and baking oven 100 provided by the present application further includes a water tank 6 in the accommodating chamber 10, the water tank 6 is used as the water source, and the water tank 6 is connected with the cabinet 1. Based on this, the steaming oven 100 further includes a first water pump 61, and the first water pump 61 is connected to the water tank 6. And the first water pump 61 is connected to the condensate box 4 through the water inlet pipe 41 to deliver cold water from the water tank 6 to the condensate box 4. The water tank 6 may also be connected to the steam generating assembly 5 by a connection pipe, i.e. in case the steam generating assembly 5 is connected to a water source as described above.

In addition, the connection between the water tank 6 and the casing 1 may be a detachable connection. Thus, the water tank 6 is convenient to be taken out and the cold water is convenient to be replenished into the water tank 6,

in this case, the above-described steam generating assembly 5 will be further described. As shown in fig. 7, the steam generating assembly 5 includes a water supply pipe 50, and one end of the water supply pipe 50 is connected to the water tank 6 and/or the water outlet pipe 42. The steam generating assembly 5 further comprises a steam generator 51 and a water vapor separator 52, wherein the steam generator 51 communicates with the other end of the water supply pipe 50. The water-vapor separator 52 is connected to the steam generator 51, and is configured to separate water vapor generated by the steam generator 51 from water vapor. When the steam generated by the steam generator 51 passes through the steam separator 52, part of water drops will flow back to the steam generator 51, and the purer steam is input into the steam baking cavity 20 of the inner container 2.

On the basis, as shown in fig. 7, the steam generating assembly 5 further includes an air supply pipe 53, and the water-vapor separator 52 communicates with the inner container 2 through the air supply pipe 53. Based on this, the relatively pure steam is introduced into the steam baking chamber 20 of the inner container 2 through the air supply pipe 53.

In addition, as shown in fig. 7, the steam generating assembly 5 further includes a second water pump 54, and the water supply pipe 50 is connected to the water outlet pipe 42 through the second water pump 54. In this way, cold water may be pumped into the steam generator 51 by the second water pump 54, and whether cold water is introduced into the steam generator 51 may be controlled by controlling the activation or deactivation of the second water pump 54.

In some embodiments of the present application, as shown in fig. 8, the steam generating assembly 5 includes a valve 55, and one end of the water supply pipe 50 is connected to each of the water tank 6 and the water outlet pipe 42 through the valve 55, wherein the water tank 6 and the valve 55 are communicated through a water pipe 60. In this case, the valve 55 includes a first state, a second state, a third state, and a fourth state. Each state is described in detail below.

When the valve 55 is in the first state, the valve 55 communicates with the water tank 6 and the water supply pipe 50, and blocks the water storage chamber 40 and the water supply pipe 50, as shown in fig. 9, so that water in the water tank 6 can flow to the valve 55 through the water pipe 60 and then enter the steam generator 51 through the water supply pipe 50, i.e., when the steam generating assembly 5 is connected to a water source.

When the valve 55 is in the second state, the valve 55 blocks the communication between the water tank 6 and the water supply pipe 50, and the water storage chamber 40 and the water supply pipe 50 are communicated through the valve 55, as shown in fig. 10, so that water in the water storage chamber 40 can flow to the valve 55 through the water outlet pipe 42 and then enter the steam generator 51 through the water supply pipe 50. I.e. in case the above-mentioned steam generating assembly 5 is connected to the outlet pipe 42. In this case, since the water in the water storage chamber 40 is used to cool the high temperature water vapor in the condensation duct 3, it is understood that the temperature of the water in the water storage chamber 40 will gradually rise when the water in the water storage chamber 40 cools the high temperature water vapor in the condensation duct 3. Therefore, the temperature of the water flowing into the steam generator 51 from the water storage chamber 40 is high, and thus the energy required for heating the water by the steam generator 51 to generate steam is reduced, thereby playing a role of saving energy.

When the valve 55 is in the third state, the valve 55 communicates the water tank 6 with the water supply pipe 50, and the valve 55 also communicates the water storage chamber 40 with the water supply pipe 50, so that water in the water tank 6 and water in the water storage chamber 40 can enter the steam generator 51 through the water supply pipe 50. In this case, the steam generator 51 may be selectively supplied with water, for example, when the water temperature in the water storage chamber 40 is low, the water in the water tank 6 may be directly used for generating steam. And when the water temperature in the water storage cavity 40 is increased, the water with higher temperature in the water storage cavity 40 can be used for generating steam, so that the purpose of saving resources is achieved.

When the valve 55 is in the fourth state, the valve 55 blocks the water tank 6 from communicating with the water supply pipe 50, and the valve 55 also blocks the water storage chamber 40 from communicating with the water supply pipe 50. In this case, the steaming oven 100 may be in a shut-off state, or the steaming oven 100 toasts food using a heating assembly.

In some embodiments of the present application, the valve 55 has a first valve port, a second valve port, and a third valve port, and the first valve port, the second valve port, and the third valve port are in bright communication. Wherein the first valve port is communicated with the steam generator 51, one end of the water supply pipe 50 is communicated with the water tank 6, and the other end is communicated with the second valve port. The end of the water outlet pipe 42 remote from the condensate box 4 communicates with the third valve opening.
